Description

Unglazed level weight sensing instrument

The utility model belongs to the improvement technology of engineering survey spirit-leveling instrument.

The spirit-leveling instrument of existing use only is beneficial to and uses under ground environment daytime from adapting to the design down of ground sunshine condition.If will be used for the environment such as night, tunnel or down-hole of unglazed conditioned disjunction dim light, just be difficult to use.Usually just have only the special messenger of employing to hold the lamp illumination,, adjust instrument and reach request for utilization to observe the state of circular bubble and coincidence level.Levelling pole stands on measurement point also need have the special messenger to hold the lamp illumination, so that telescope can be read scale and numeral on the scale.Operation is trouble comparatively, and visual range is limited, and division line on the levelling pole and numeral are not distinct yet, and sharpness is just poor.Cause work efficiency low, labour intensity is big, also may influence measuring accuracy.

The purpose of this utility model just provides and a kind ofly installs illuminating device additional on the body of existing spirit-leveling instrument, and existing levelling pole face is made the strong levelling pole of reflecting effect, makes it to become the spirit-leveling instrument that carries out engineering survey under the no luminous environments such as adapting to tunnel, down-hole or night.

The scheme that realizes above-mentioned purpose is as follows:

This hydrolevelling device is made of spirit-leveling instrument and levelling pole two parts, key is on the body of spirit-leveling instrument, the top that is positioned at circular bubble is manufactured with the base of a light emitting diode, light emitting diode to circular bubble illumination is installed, at one of the housing installed inside of coincidence level be used to the to throw light on light emitting diode of coincidence level in the base; In telescope one side the spotlight that can produce approximate parallel beam is installed by support; The chi face of levelling pole adopts light converse luminescent material or luminescent materials, and division line on the chi face and numeral are made with common dark raw material.

Further scheme is that the spotlight on the spirit-leveling instrument is made of flashlight type concave mirror, lamp socket, outer cover and bulb etc.; The support that spotlight is installed is a web joint that laterally extends from spirit-leveling instrument body front end, be equipped with on support and be used to the parallel beam adjusting screw parallel with telescope optic axis that spotlight is sent, lamp socket makes convex surface with the joint portion of support and concave curved surface combines.On the coincidence level outer cover, a battery compartment is installed, the side is equipped with the power switch that is respectively applied for control spotlight and coincidence level light emitting diode, flattens the circular bubble light emitting diode.

Is as support according to such scheme at web joint of instrument body front end horizontal expansion to the improved mode of automatic compensated level, rack-mount with three adjusting screws spotlight, an affixed light emitting diode lamp socket on the body that is positioned at above the circular bubble, one of attaching is used for the light emitting diode of circular bubble illumination in it; The power switch of difference attaching spotlight and circular bubble illuminating lamp on organism sidewall; Battery compartment is installed in body one side.

Is as the spotlight support according to such scheme web joint of body front end horizontal expansion for the improved procedure of digital level, with three adjusting screws spotlight is installed on support equally, a spotlight power control switch is installed on organism sidewall, with lead they and the original power supply of instrument is connected and get final product.

The chi face of levelling pole is with converse luminescent material or luminescent materials, and division line and numeral adopt dark common material to make, so that when measuring, obtain reading clearly from telescope.Because digital level is that computer reads measurement data automatically, employed levelling pole also is a machine-readable yardstick, therefore, uses for it is adapted in the no luminous environment, and its yardstick is also used converse luminescent material or luminescent materials.After making levelling pole in use be subjected to the spotlight irradiation of spirit-leveling instrument, produce distinct strong measurement barcode signal.

Can finish improvement according to such scheme, make it to become and have survey measurements illumination and level illumination function easily automatically, be adapted to not have at tunnel, down-hole or night and make the normally hydrolevelling device of measurement luminous environment under existing hydrolevelling device.

The utility model has the advantages that owing to set up illuminating device for circular bubble, the coincidence level of existing spirit-leveling instrument, and the light beam that sends has been installed can the spotlight parallel with telescope optic axis, the levelling pole face is with converse light or luminescent materials.Make the existing hydrolevelling device after the improvement, both be adapted to the ground survey work under the sunshine condition, be adapted to again not have in the luminous environment at tunnel, down-hole or night and measure.When under no optical condition, using, not only the normal running adjustment of spirit-leveling instrument becomes very convenient, and, the light beam irradiates parallel with telescope optic axis that spotlight sends is to the levelling pole face, telescope has also just been aimed at levelling pole, the strong reflecting effect of levelling pole face makes that observed reading distinctness is clear from telescope, improves measuring accuracy; The simultaneously-measured distance of distinct vision can increase greatly.Reduce the denominator measuring instrument in using at tunnel, down-hole, night, also must the special messenger hold the trouble that lamp throws light on.
